There seems to be a problem with this on gcc-4.4.3. See, for instance,
[http://beta.boost.org/development/tests/release/developer/output/Sandia-
gcc-4-4-3_0x-boost-bin-v2-libs-spirit-test-karma_actions-p2-test-gcc-4-4
-3_0x-debug-karma.html this]. Michel, can you please look into this soon?
We're about to lock down the release branch for 1.48, and I hate to
regress Boost.Foreach.
